The processing system of the doubletoothed roller crusher makes it possible to crush any type of raw material from hard (limestone and rock) to soft (clay, soil and mud) or even elasticlike wood or rubber tyres. The rotation speed, especially if compared to traditional crushers, is very low; so low, in fact, that tip speed is under 3 m/s.
